摘要 根据数字电视OFDM信号对电视发射机功率放大器线性的要求,介绍了一种可识别功放记忆效应的数字预失真器的结构和特点。经过计算机仿真表明,记忆效应预失真结构应用在数字电视发射机功放的线性化中可以取得令人满意的效果。 The article introduces the structure and characteristics of Digital Pre-distortion(DPD).DPD can identify memory effects of power amplifier (PA),and meets the linear requirement for television transmitter power amplifier to transmit digital television OFDM signal.Through computer simulation,it is verified that the application of memory DPD structure for power amplifiers in Digital TV transmitter can achieve a satisfactory result.
